Title: 27-halo derivatives of ll-f28249 compounds
Inventor: ASATO GORO
IPC: C07H19/01
Filed: 1988-03-04
Granted: 1991-07-09
Abstract: ABSTRACT The  present  invention  relates  to  novel derivatives of LL-F28249 compounds wherein the pendent C(26,27) olefinic group at C(25)  is converted into a 27-bromo or 27-chloro-26-methylene group.  The 27-bromo compounds are derived by reacting the LL-F28249 com-pounds or 5-0-trisubstituted silyl LL-F28249 compounds with N-bromoacetamide or N-bromosuccinimide in aqueous acetone,   followed  by  desilylation  for  silylated LL-F28249 intermediates.  The 27-chloro compounds are prepared by reacting LL-F28249 compounds with N-chloro-succinimide in methanol.  These novel halo compounds have anthelmintic,  ectoparasitic,  insecticidal,  nema-ticidal and acaricidal activity and are also useful intermediates  for  the  preparation  of  other  novel biologically active compounds.  Compositions containing the present compounds as active ingredients thereof are presented.

Granted: 1994-03-08
Abstract: ABSTRACT OF THE DISCLOSURE            A method is disclosed for arranging a read memory for reading electrically update status information from an integrated circuit which comprises various circuit layers.  Patterned circuit layers, so-called pattern layers, are produced, for instance, from a respective mask which has been made for each of the pattern layers.  Each pattern layer in which reconstruction can be made has provided therein a separate memory device such that when chances are made in one such pattern layer, the updating status of the pattern layer can be written into the memory device in code form.  The memory devices included in an integrated circuit form a read-only-memory which is programmed so that the pattern layers in which a memory device is provided contain a code which is unique to its own update status.  At the same time as the updating status code is written into the memory device, the code is also written into a test device as reference information.  When checking the circuit, a test program in the test device reads the update status of the pattern layers and compares it with the reference information, the result of this comparison indicating the update status of the integrated circuit.
